Height 5'6 weights 147.5lbs what is my bmi?

24. These numbers were actually never intended for individuals, but as a measure for populations. Your best weight is what looks and feels right to you and lets you take part effectively in your favorite sport. As a predictor of health, the much-sought-after "appropriate bmi" of 18-25 has been a disappointment. It's much more important simply to stay physically fit. Best wishes.
